General informations

The Linux kernel configuration item CONFIG_STM32_DMAMUX has multiple definitions:

STMicroelectronics STM32 DMA multiplexer support found in drivers/dma/stm32/Kconfig

The configuration item CONFIG_STM32_DMAMUX:

• prompt: STMicroelectronics STM32 DMA multiplexer support
• type: bool
• depends on: CONFIG_STM32_DMA
• defined in drivers/dma/stm32/Kconfig
• found in Linux kernels: 6.11–6.12, 6.13-rc+HEAD

Help text

Enable support for the on-chip DMA multiplexer on STMicroelectronics STM32 platforms. If you have a board based on STM32 SoC with such DMA multiplexer and want to use DMAMUX say Y here.
